It's a adventure game where you go into dungeons, fight monsters, loot chests and items, upgrade and level your char. Also, the game offers a possibility to earn a few bucks. Here's how it works.
On the last day of each month all of your looted gold is converted into cash, so say 400k gold equals about a dollar. Then everything resets and on the first day of the next month you start over again. But It's pretty fun. There are many extra events and contests to participate in. You can join wars and trade with other players.
Anyway, if you like those type of games, try it out.
Oh and feel free to message me here or on the game (since my username there is the same) for any tips or guides, I'll be happy to help!
